--- name: arabic-design description: Make AI-generated designs render Arabic text correctly — clean, connected, professional. Fixes the letter-spacing trap that breaks connected script, wrong font fallbacks, clipped diacritics, and RTL/bidi bugs in mixed Arabic+English text. Use whenever generating or styling ANY Arabic text in HTML/CSS/React/UI — especially when Arabic "looks broken", letters overlap or disconnect, words render in the wrong order, or diacritics get clipped. --- # Arabic Design — clean Arabic in AI-generated UI Arabic is a **cursive, connected script**: letters join, and diacritics (ً ّ َ) sit above/below the baseline. Most AI-generated CSS is tuned for Latin type — and that's exactly what breaks Arabic. Apply these rules by default whenever the design contains Arabic; don't wait to be told. ## Rule 1 — NEVER negative `letter-spacing` on Arabic (the #1 bug) Latin design trends love tight tracking (`letter-spacing: -0.02em`). On Arabic, negative tracking overlaps the letter joins and crushes words into an unreadable blur. Positive tracking is just as wrong — it *disconnects* letters that must join. ```css /* ❌ WRONG — crushes connected letters into a blur */ h1 { letter-spacing: -1.5px; } /* element contains Arabic */ /* ✅ RIGHT */ h1 { letter-spacing: normal; } /* or 0 — always, for any element containing Arabic */ ``` - Any element containing Arabic (or mixed Arabic+Latin) → `letter-spacing: normal`. Full stop. - Negative/positive tracking is allowed **only** on pure-Latin/numeric elements (big stat numbers, `$99`, `VS`, all-caps Latin labels). ## Rule 2 — Use a real Arabic font (never Latin-font fallback) A Latin font with no Arabic glyphs silently falls back to a system font — mismatched weight, broken look. Always declare an Arabic-capable font explicitly, with a full stack: ```css /* pick one that matches the design's mood: */ font-family: "Cairo", "Tajawal", "IBM Plex Sans Arabic", "Noto Kufi Arabic", sans-serif; /* modern UI */ font-family: "Almarai", "Rubik", "Baloo Bhaijaan 2", sans-serif; /* rounded/friendly */ font-family: "Noto Naskh Arabic", "Amiri", serif; /* editorial/classic */ ``` - Load the Arabic weights you actually use (400/700 at minimum). - Never apply `font-style: italic` to Arabic (fake oblique breaks the script) and never rely on `text-transform` (Arabic has no case). ## Rule 3 — Line-height must clear the diacritics Bold display Arabic needs vertical room, or dots/diacritics collide with the line above. | Context | Safe line-height | |---|---| | Display headline (large, bold) | **1.3** | | Mid headline | 1.35 | | Body / captions | 1.5–1.7 | If unsure, go looser. Clipped diacritics are an instant "looks broken" tell. ## Rule 4 — Direction & bidi (the "words are reversed" family of bugs) - Set direction **once at the root** (`` for Arabic-first pages) — children inherit. Don't sprinkle `dir` attributes on every element. - Use **logical CSS properties** so layout flips correctly: `margin-inline-start`, `padding-inline-end`, `text-align: start` — instead of `margin-left`, `text-align: left`. - Wrap embedded **Latin words/numbers** inside Arabic text in an isolated span so the bidi algorithm doesn't reorder them: ```css .ltr { display: inline-block; direction: ltr; } ``` ```html حدد أول MVP قبل ما تبدأ ``` - **The `direction: ltr` parent leak** (root cause of reversed word order): layout containers set to `direction: ltr` for card/column order leak LTR into the Arabic text inside — so `Marketplace مدمج` renders as `مدمج Marketplace`. Fix: LTR only for *layout order*; every Arabic **text** block inside gets explicit `direction: rtl`. - **The `الـ` + Latin-word trap:** never place the Arabic definite-article prefix (`الـ`, `بالـ`, `للـ`) immediately before an isolated Latin word — the detached letters jump to the wrong side. Drop the article (`عبر CLI` not `عبر الـ CLI`) or rephrase. - Flip directional icons (arrows) in RTL contexts; a "next" arrow points left in Arabic UI. ## Rule 5 — Punctuation & line breaks - Use Arabic punctuation in Arabic sentences: `؟` not `?`, `،` not `,`. - If a `?` or `،` floats to the wrong side, the cause is almost always a straddling Latin token — wrap it in `.ltr` or rephrase so the sentence doesn't break mid-clause around it. - When splitting a headline across lines, each line must continue the sentence naturally — Arabic readers read stacked lines as one flowing thought. ## Rule 6 — Mobile legibility Arabic letterforms are denser than Latin at the same px size. For social/mobile canvases (e.g. 1080px wide), keep body text ≥ ~36–40px and prefer heavier weights (600–800) for display text. --- ## Pre-ship checklist 1. No negative `letter-spacing` on any Arabic-containing selector: ```bash grep -nE "letter-spacing:\s*-" file.html ``` Every hit must be pure-Latin/numeric. If it wraps Arabic → `normal`. 2. Every Arabic element has an explicit Arabic-capable `font-family`. 3. Display Arabic has line-height ≥ 1.3; body ≥ 1.5. 4. Embedded Latin words/numbers wrapped in `.ltr`; no `الـ/بالـ/للـ` directly before a Latin word: ```bash grep -noE "(الـ|بالـ|للـ) ?
